IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROJECTION APPARATUS

摘要

A first sum is calculated which is a sum of light intensities of dispersed lights generated when a pixel light by a target pixel passes through an optical system, and a first light intensity is calculated by adding the first sum to a light intensity of the pixel light of the target pixel. A second sum is calculated which is a sum, at a position of the target pixel, of each of light intensities of dispersed lights generated when each of pixel lights by pixels around the target pixel pass through the optical system. A second light intensity of the pixel light by the target pixel is calculated by subtracting the second sum from the first light intensity.

主权项

1. An image processing device comprising:
a first calculation unit that calculates a first sum which is a sum of light intensities of dispersed lights generated when a pixel light by a target pixel passes through an optical system, based on distance from the target pixel, to calculate a first light intensity by adding the first sum to a light intensity of the pixel light; a second calculation unit that calculates a second sum which is a sum, at a position of the target pixel, of each of light intensities of dispersed lights generated when each of pixel lights by pixels around the target pixel pass through the optical system, based on distance from the target pixel; and a combining unit that calculates a second light intensity of the pixel light by the target pixel by subtracting the second sum from the first light intensity.
